IM PROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 215.913, dated May 27, 1879; application filed December 28, 1878.

To all whom it may concern:

Be it known that I, WILLIAM W. GooDWIN, of Greston, in the county of Union and State of Iowa, have invented a new and valuable Improvement in Corn-Planters; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a top plan of my corn-planter, and Fig. 2 is a detail view of the same.

My invention relates to a corn or seed planter; and the novelty consists in the construction and arrangement of parts, as will be more fully hereinafter set forth, and pointed out in the claims.

In carrying out my invention I employ a driving-shaft, rigid with the running-wheels, on which I hang a hand-wheel having cams on opposite sides, which operate to vibrate the feed-bar as said cams engage alternately with a hinged jaw.

When the machine is backed, the abrupt ends of the cams operate to raise the hinged jaw out of connection, and the vibrations of the feed-bar cease.

A rack-wheel rigid on the drivin g-shaft acts in connection with a spring-pawl on the handwheel, and serves to force the hand-wheel to revolve with it in one direction, while the pawl rides idly over the ratchets in the other. Arms upon the hand-wheel allow the driver to turn said wheel in the reverse direction, to arrange the hills to suit.

A rock-shaft is provided at the front with footlevers and at the rear with arms, which operate pivoted levers, to which are attached hinged arms having marking-blocks. By this arrangement the driver may readily mark upon the side, as a guide to drive by, and change from one side to the other by simply using his feet, as when one marker is down the other is up.

' Referring to the drawings, A represents the driving-shaft, rigid with the wheels at m, and journaled in the frame A of a corn-planter. Upon this shaft A, and rigid therewith, is a ratchet-wheel, B, which engages a springpawl, 1), upon a hand-wheel, 0, having cams 0 upon opposite sides, and arms 0, as shown.

When the wheels 00 and driving-shaft A revolve in a forward direction, the spring-pawl b engages the ratchet-wheel B, and causes the hand-wheel to revolve in the same direction. In such case the inclined sides'of the cams c operate upon a hinged jaw, D, alternately. This jaw is hinged to a pivoted arm, D, the forward end of which operates in a staple, 6,

upon the feed-bar E. In backing, the abrupt or radial ends of these cams c act upon the hinged jaw and raise it out of engagement.

In turning at the ends of the rows, the revolutions of the running-wheels vary, and when starting again to plant, the hills do not come in line with the previously-planted hills. In such case the driver grasps the arms 0, and turns the hand-wheel C backward a proper distance, as is obvious.

The shoe F is of ordinary construction, except that it is provided with a removable adjustable foot, f, as shown.

G represents a rock-shaft, journaled in the frame, having on its forward end foot-levers g g, and on the rear end arms g g, which operate pivoted levers G G, having hinged markers H, with feet h.

I am aware that a forked arm operated by a wheel having cams upon opposite sides has been employed to work the feed-slide in a corn-planter, as shown in Patent No. 139,205, May 20, 1873, and also that a seed-wheel has been provided with a pawl and ratchet-wheel, as shown in Patent N 0. 86,386, February 2, 1869, neither of which constructions are broadly claimed herein.

What I claim as new, and desire to secure by Letters Patent, is

1. The driving-shaft A,ratchet-wheel B, and spring-pawl b, in combination with the handwheel 0, having cams 0 and arms 0, and with the hinged jaw D, arm D, and feed-bar, as and for the purpose set forth.

2. The rock-shaft Gr, having foot-levers g g and arms 9 g, in combination with pivoted levers G G and hinged markers H h, as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
